Steele has been diagnosed with left elbow inflammation following an MRI, Paul Sullivan of the Chicago Tribune reports.
He will undergo additional imaging, but the left-hander received good news from the initial test results. Steele had to be scratched from a scheduled start Tuesday versus the Pirates due to elbow soreness, which he admitted he's been dealing with for a while. No decision has been made regarding a potential stint on the 15-day injured list, but it's a move that seems likely. Kyle Hendricks is starting in Steele's place Tuesday.
